Suppress the pathfinder INFO summary on repeats, not on plugin presence

[LeSingh1]

def pytest_terminal_summary(terminalreporter, exitstatus, config):
    if not config.getoption("verbose"):
        return
    if hasattr(config.option, "iterations"):  # pytest-freethreaded runs all tests at least twice
        return
    if getattr(config.option, "count", 1) > 1:  # pytest-repeat
        return

The comment states the intent: suppress the summary only when the run repeats tests.
The pytest-repeat line implements exactly that (count > 1). The pytest-freethreaded line
checks only that the option exists.

--iterations is registered by the plugin with a default of 1, so merely having
pytest-freethreaded installed suppresses the summary on an ordinary pytest -v run — no
repetition required.

That matters because the INFO summary is the only output of the info_summary_append
fixture, which test_load_nvidia_dynamic_lib, test_driver_lib_loading,
test_find_nvidia_headers, test_find_static_lib and test_find_bitcode_lib use to
report what they actually discovered on the host. It would silently disappear.

The plugin is not currently in cuda_pathfinder's test dependency group
(pytest, pytest-mock, pytest-repeat, pytest-randomly), so this is dormant today —
but #2114 moves the repo toward parallel-test plugins, and pytest.ini already registers
the thread_unsafe / parallel_threads_limit markers, so it is worth having right before
that lands rather than after.

Fix

Make the check symmetric with the pytest-repeat one:
getattr(config.option, "iterations", 1) > 1.

Test

New cuda_pathfinder/tests/test_conftest_info_summary.py drives the hook directly with
stub config / terminalreporter objects — no plugin install and no CUDA needed — across
the matrix of plugin absent / present-with-1 / present-with-2 for both plugins, plus the
-v gate.

Two of its cases (freethreaded-single, both-single) fail on main: the summary is
suppressed even though nothing repeats.

Verified: pytest cuda_pathfinder/tests has the same pass/fail set as main otherwise;
ruff check, ruff format --check and the pre-commit mypy-pathfinder invocation are all
clean.
